BMS not fully utilising my GTX 1070
-
So after I changed my GPU from the 980 Ti to the 1070, I made sure that I deinstalled the old driver, rebooted my system, installed the new driver and rebooted m computer again.
And of course, I immediately started “GPU tweak” from ASUS to get a good overclocking and to see, how much the GPU is used and how it behaves.
After I got the right overclock and made sure, it’s stable, I tested some games.
Other sims and games work ok, GPU is used like 99%, GPU and memory clock are going up and stay stable at those clockspeeds.
Then i tried BMS, with the same settings as I had them with my 980 Ti.
With the 980 Ti, I achieved stable FPS and mostly 60 FPS. But when I tried BMS with the 1070, I only achieved 48 FPS in the empty dogfight scenario. I checked my BMS settings, which are mostly still default and the same as with the 980 Ti and thought, HOW?
Then I took a look at “GPU Tweak” and saw something weird. GPU utilisation was maximum 90% going up and down, but mostly was going from 20% up to 80% and immediately dropped again and back up and again and again. Temps were with 40 degrees celsius more than good. Memory clock was also like the usage going like crazy up to maximum clock and back down to idle. GPU voltage was with 650 mV ok and the GPU clock was always idling and never went up.
Then I discovered this thread here: https://www.benchmarksims.org/forum/showthread.php?27834-MSI-GTX-1080-Gaming-X-poor-performance-in-3D-cockpit-any-idea-!&highlight=1070
The thing is, I haven’t overclocked my CPU. And I know BMS uses quite a bit more CPU and GPU, but since i didn’t change my CPU, i wasn’t expecting something like that…
Also, I disabled the IGPU from my CPU and made sure that in BMS the 1070 is selected. And I’ve set my computer on power and not energy saving.
So far, BMS is the only software that I have some “bad” performance with it. Anybody has some suggestions that I should try?
-
Wild guessing: energy saving automatism of the gfx card?

Never heard of that…
I have my own profile, GPU voltage is set to 100% and power target to 120% if you mean something like that.
But why would it save energy when BMS is running but not when other games/sims/softwares do?
-
I’m pretty certain BMS in its current state will or can never push that kind of GPU hardware to its limits.
I believe the API’s will be the bottleneck.
-
I know that BMS will most likely not be able to pull everything from a GPU or high-end system. But since the 1070 has a similar performance to the 980 Ti, I was expecting more or less the same performance. My 980 Ti wasn’t fully utilised too, but the clock speeds weren’t at idle speed so I was able to achieve a better performance.
-
It seems quite a few games will do better on a 980ti vs an 1070. 1070 is a sideways upgrade and often a step down from 980ti for gaming, but better on power consumption.

Seems like the idling GPU clock wasn’t the problem but the software that displayed it…
Anyway, looks like i’m going to throw my 980 Ti back in…

Change energy managing from saving to maximum performance in your nvidia control panel. U can make program specific settings. Same applies to Dcs, Arma, etc.
I have a 1070 and Falcon runs at average 100 fps in campaign and thats with I7 3770 CPU and 16 gig mem.
Best of luck

I’ve upgraded to a new rig containing a 1080 and i7 4Ghz, with latest nvidia drivers, default gpu/cpu settings, full bms options, I got 60 fps everywhere all the time with game res 2560x1080. Doing some deeper research (check far below) it seems that this “limit” is set according to the monitor default refresh rate too. I’ve then tested disable vsync and go for some test flights, fps were from 160 minimum to 240 max, no other options changed at this point like overclocking cpu/gpu etc.
Although these fps were indeed alien to me (the only similar case experiencing 240 fps was in an friend’s older rig back in OF days, using amd and ati mid-range eq), I’ve noticed (actually “confirmed” ) that when for example moving head from side to side quickly with Track IR the monitor of course could not follow the image frames updates, resulting in “broken frames” in the 3D world, which although not noticeable in most of the cases (e.g. straight flight, high altitudes etc) was somewhat annoying in lower altitudes or dynamic head positioning situations.
My current “compromise” is to force monitor go from 60 to 75 fps (tested and is supported, check links below), turn back on vsync and enjoy the always stable new 75fps limit in my setup. Next steps will be to check overclocking the system only to check (disabling vsync so to confirm) what new fps limits it can reach above 240fps.
EDIT: Also just to mention that test flights were made with 2 setups: 1. default 4.33 Korea with default models, and 2. Ikaros new wip version containing new JanHas heavy viper models, no differences on end fps. Same goes for TGP, FLIR and Weapon MFD selections/images, no impact to see fps drops.
You might want to review these as a start for some extra info:

Hope to help a bit.

Should 1070 be stronger than 980 TI ? I’m not so sure…
And yes, BMS engine at it’s current state will not utilize the GPU fully, never. The GPU depends on calls from the application, and if application has stalls then GPU won’t be fully utilized.
Besides that, while I don’t know other flight simulators that good, mostly they will be CPU intensive, and any application with intensive CPU work will probably not be able to fully utilize the GPU, as the CPU may not be able to push enough work for the GPU to keep it busy all the time. 100% utilizing the GPU I’d expect from 100% GFX applications and/or some relatively CPU light games like most FPS (i.e I can clearly hear the GPU screams at my son’s PC when he is playing COD/BF).

That was what i meaned in my first post.
Regarding 980TI / 1070: looking at benchmarks from different games the 980 is often faster than the 1070.

Hi razo, there is Something you can easy try and wich works for other games (DCS, gta5,…) when gpu is at low usage while fps are bad : do a new nvidia driver install with custom settings : only drivers and complete new install (will delete all old files) - the problem in these cases being GeForce experience.
So in some games (others works ok) without GeForce experience installed your gpu will now load fully before experiencing fps drops - with 60hz vsync on you should have 60fps until the gpu hit 100% usage - maybe you have the case with bms. Maybe it’s not your problem ? -
I have exactly the same problem, but with a 1080 card.
Tried everything: Nothing has helped so far.
If I set driver-controlled AA to a specific setting like 4x MSAA / 4x SGSSAA I even drop to the 25 FPS limit in the AGM 65-TE.It happens in Windowed (with Display Extraction Mode) and Full Screen Mode.
GPU Usage is always relatively low (even with aggressive AA settings).
Did anyone experience and solve this yet?

But what CPU is driving the GPU ??

Hi Shadow - thanks for the quick reply!
I use a 5820k - not overclocked. Everything is fine in other Games.
4K resolution. Same effect with every driver that I used until now. Even with the latest drivers.One suspicious thing: when I used MSI Afterburner to show the FPS, the number where way higher than the one BMS stated. I think that this was due to the windowed mode.
I also used a 980Ti before without problems.

BMS with the 1070, I only achieved 48 FPS in the empty dogfight scenario
120-140 FPS with GTX570
Sounds for me like wrong or overkill settings in GFX control panel / bms configurator …

BMS was not build nor optimized for those new cards or videos, and it goes the other way around, GTX 1xxx doesn’t take advantage of BMS.

Nice. As Arty comments this is old software.
I have always believed 4.0 at times ran better on the older hardware with the right drivers.
BMS/F4 is a single threaded app running on multi core cpus.
Im always happy when I’m flying with better then 25fps. It doesn’t need 120FPS, whats the point.
PS: the 3 core 720 Phenom @ 3.6Ghz was the last CPU which gave me a boost from core numbers. The 4 core 940 Phenom @ 3.8 brought no improvement.

Hi Arty, that sounds quite logical, though others seem to have them working with quite high FPS numbers at the same resolution and similar settings.
Maybe it depends on the model? I use a MSI 1080 Gaming X which is quite a powerful card.Cheers,

Hi Shadow,
thanks for the quick reply.
I can also live with a lower FPS count - no problem. As long as I can maintain a stable 30 I’m fine. I only really care about my IR Tracking device working smoothly.
The lower GPU usage also has the advantage that it works quietly because it doesn’t get too hot.Nevertheless: I’m well aware of the limitations of older DX9-based software. It’s just that this doesn’t really seem to be the problem in my very case:
1. Others with the same chip don’t have these problems - their cards perform at maximum GPU usage
2. If I use very high AA driver settings GPU usage still doesn’t seem to increase while FPS stay in the lower-to-mid 20s.Thanks,
SP
